Voltage Rating
230 V | 460 V
60 Hz three-phase operation with dual voltage rating (230 V or 460 V) gives you one motor for multiple facilities and drives, reducing spare parts and stocking complexity. This 1 HP motor delivers steady torque at 1155 r/min, supporting conveyors, pumps, and fans without over-sizing. The rated efficiency of 82.5% and a 1.15 service factor translate to tangible energy savings and higher uptime. Frame size 145TC with a C-face drive end and foot mounting simplifies replacement and retrofits, enabling quick installation in existing CNCs, gear reducers, and open-frame machines. The OPSB enclosure enables robust protection while maintaining accessibility for servicing and cooling in open plant environments. Insulation class F and continuous duty capability reinforce reliability under elevated ambient temperatures up to 40 °C, while 3-phase 60 Hz operation aligns with standard electrical infrastructure. High-quality bearings (6205 ball; NDE 6203 ball) and a 0.88 in shaft diameter support longevity and smoother torque delivery in demanding lines. Stocking at U.S. and international warehouses reduces lead times, improving procurement predictability and maintenance planning.
